I have modelled ac motor with equations in simulink, and i have designed inverter in specialized technology which comes under simscape Power systems, Iam unable to connect simulink motor equations with simscape inverter..Pls suggest me a solution..

Share your model.

Iam unable to connect motor which i have modelled as equations, with three legs of inverter...this is my research topic sir..

[Izuchukwu Eze]

I'm having similar problem with you. I modelled permanent magnet synchronous motor using the necessary equations in simulink together with inverter but I could not connect the output of the inverter to the input of the PMSM even though I have tried PS-Simulink and Simulink-PS. It could not interface between the two. Can someone help a stuck brother. My research has been impeded because of this.

Simulink and Simscape connections are different since their signal domains are different. In order to convert them compatible for one another, use PS-Simulink Converter or Simulink-PS Converter. Check them from the following link:

Sir, Thank u responding..These converter insist some sensors to be connected..But still iam unable to connect..

[Birdman]

If you do not share your simulink model, I can not help anymore.

[R.Deepa Ramesh Babu]

Herewith iam attaching my model sir..In this model i have connected Induction motor available in specialized technology block..Now I have modelled motor with equations, which iam unable to connect..

[Birdman]

Everything seems connected. Which parts are unconnected?

[R.Deepa Ramesh Babu]

Same induction motor is not used now..induction motor is modelled with equations..these equations iam unable to connect with three legs of inverter..

[Birdman]

But you need to share with me the model that you can not connect. What should I do with this?

[R.Deepa Ramesh Babu]

Sir, Iam attaching the model..Connection port 1 , 2 ,3 cannot be connected to Va, Vb, Vc of synchronous reluctance motor(SyRM)..I have modelled SyRM with equations..

[R.Deepa Ramesh Babu]

Sir, A Kind remembrance, Have u received the model..

Hello sir, did you find a way around this? I also need help on this
